.To all whom it may concern:

Be it known that l, ALBERT B. HERnIoK,

a citizen of the United States, resident of (leveland, county ofCuyahoga, and State of 3 Ohio, have invented a new and usefulImprovement in Clamping and Heating Devices, of which the following is aspecification, the rinciple of the invention being herein eirpihined andthe best mode in which I have contemplated applying that principle, soas to distinguish it from other inventions.

My invention relates to means for effecting a homogeneous mechanicaljuncture between metal bodies and particularly to means for 1 clampingand heating a rail bond to two abutting rails for the purpose ofsoldering or brazing the same to the latter.

The object of the said invention is to provide mechanism whereby suchclamping and heating may be effected in an economical and efficientmanner.

Said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawings and the following description set'forth in detail.certain means embodying the invention, such disclosed means however,constituting but one'of the various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings :Figure 1 rep resents a plan viewof a deviceembodying my invention, showing also a portion of two abutting rails.Fig. 2 represents a side elevation of the same partly broken away, twoabutting rail ends and a rail bond in position, being also showntherein. Fig. 3 represents an end view of such device in connection witha bond, and a section of the rail. Figs. 4, 5, and 6 represent persective detail views of parts of said device. igs. 7 and 8 respectivelyrepresent a side elevation and an end view of a bond such as is used inconnection with my said invention to join the ends of such rails. j

The process of bonding rails which is used in connection with theinvention about to be described is fully set forth and claimed in myco-pending application filed November 25, 1904, Serial No. 234,161, andneed hence be but briefly described herein. Said process consists inplacing the bond in contact with the adjacent ends of the rails to bejoined, a suitabe brazing or soldering medium being first interposedbetween the bond and such" rail ends, a block or similar support havinga high electrical resistance is then brought to bear upon the bond tohold it firmly against the rail, and, finally an electric current ispassed through block and bond. The means so for effecting this processconsists of the following device:

A rigid support A is provided with an undercut bearing (1 adapted toreceive a similarly formed member, not shown, that is mounted uponmechanism attached to a suitable carriage such as a car so' as to allowthe said support to be swung upon the arc of a circle and also movedtoward and from a vertical plane passing through and parallel with therail. This mechanism will be made the subject matter of a separateapplication for U. S. Letters Patent and need not be further describedherein.

' In the upper part of 'the support A is threaded a screw a providedwith a hand wheel a by means of which the said support may be clamped tothe member upon which it slides, the bore in which such screw o isthreaded intersecting the undercut bearing a 89 as is indicated in Figs.1 and 3. By this means it can be readily seen that the support and partsattached thereto may be secured in various positions upon the member onwhich it is mounted,

Secured upon a surface a formed by a de- )ress'ion cut in support A andintersecting ihe lower end thereof are two yielding members or stops a",a which curve outwardly, as shown. These stops are bifurcated as '90shown in Fig. 5 and have their lower ends projecting downwardly from thelower end of the support A. Secured to the upper part of the support Aare two flexible laminated conductors A, A of flat plate-likeconstruction, as shown, to the lower end of each of which is secured ina suitable manner as by bolts a a and a washer a a slotted carbonholder13. To the inner face of each of these holders is secured a rectangularblock of carbon '1) having a free contact surface I), as shown in Fig.6. Intermediately of its extremities each conductor A is formed with asmooth bore through which projects a screw a provided with a hand-wheela The inner end of this screw passes between the bifurcations of thecontiguous spring stop a and is threaded into the support A, as shown inFig. 3. By means of this manually operated screw the flexible conductorA may be flexed so as-to bend in'wardly thereby tilting l I adjustedagainst the sides of two abutting 4 ment, as will be readily understood.

tinctly claim as m invent1on:

' 'movably restin against the same at another and resting against stopmember,vmeans for bination of a support, a yielding stop memthe carbon12, as described in my above-menticiaged application of process ofbonding ra I By having the stopa, against which conductor A rests, offlexible construction as described, the lower end of such conductor andattached carbon is not only'tilted when screw 11 is drawn up butis alsomoved inwardly toward,the rail. This construction hence permits the twocarbons to be properly rails when their sides are not in exact aline-;

In utilizing the above mechanism for carrying out my said process the suport A is" suitably connected with a source 0 electrical energy, therebyintroducing the conductors A and carbons 6 into an electrical circuitwhen a bond is interposed-between such carbons and the rails and contactestablished, between them, as shown in 3, the said support, conductors,and carbons being connected electrically with each other in seiiesQOther modes of applying the dprinciple of my invention may e employsinstead of the one explained, change eing made as regards the meansherein disclosed,'- rovidedthe means stated by any one of the ollowingclaims or the equivalent of such stated means be employed. J

I'th'erefore particularly point out and dis- 1. In adevice or bondingrails, the -co1n hination'of a support, a'flexible conductor membersecured at one end thereto means for flexing said member to tilt thetree end thereof, and a high resistance medium mounted u on such freeend.

2.

'3. In a device forbonding rails, the combination of asu'pport, a yie ding-stop memberattached thereto, a flexible conductor member secured at one end to saidsupport adjusting the position of the free end of said member, and ahigh resistance medium mounted u on such free end.

4. In a evice for bondin rails, the comber attached thereto, a flexibleconductormember secured at one end to said support and resting againstsaid stop member, a screw mounted in said. support and engaging saidconductor member intermediately of its pointbf attachment 'and said stopmember, and a high resistance medium mounted a high resistance mediummounted upon the free end of said conductor member, and

means for adjusting the position ofthe free end of said member to securea rail-bond between the resistance medium-borne thereby and such rails,said conductor member, re-
